His approach relies on the physical act of drawing. In works like Key Note Speech and Mixing Semi-Fours, Himmelfarb uses dense clusters of lines to build form. He often works with ink and brush. This allows the fluid nature of the medium to dictate the tempo of the composition. His style sits between abstraction and figuration. While some marks suggest human figures, others remain purely gestural. This creates a sense of movement across the paper.

Modern collectors find interest in the intellectual curiosity of his prints. His work fits contemporary interiors because it offers visual complexity without relying on traditional representational tropes. Pieces such as Eyeland and Turandot's Riddles provide a balance of graphic weight and open space. The neutral colours make his art adaptable to different architectural settings. His prints invite observation of the individual stroke and the larger structure.
